OILING DEVICE.

Application filed July 17, 1913.

Specification of Letters Patent.

Serial No. 779,483.

To all whom it may concern:

Be it known that I, JAMns CATTERALL, a citizen of the United States, residing at Fisherville, in the county of Worcester and State of Massachusetts, have invented a new and useful Oiling Device, of which the following is a specification.

This invention relates to an oiling device and particularly to a device for supplying oil to the rotary cylindrical cutter of a cloth shearing machine or to other similar mechanism. In such machines, it is necessary to provide a very slight but continuous supply of oil throughout the entire length of the rotating member. Devices have been heretofore used which have depended entirely upon manual feed for the distribution of oil thereto but they have been found irregular and wasteful in operation and have been otherwise unsatisfactory.

It is one of the objects of my invention to provide an oiling device of the class described which is not dependent for its oil supply upon constant manual manipulation, which is regular and continuous in operation and which may be cheaply manufac tured and easily attached to different machines.

My invention consists of the devices, combinations, and arrangements of parts hereinafter described and more fully set forth in the appended claims.

A preferred form of my invention is shown in the drawings in which Figure 1 is a front elevation of my device, part-s thereof being broken away to show the interior construction: Fig. 2 is a sectional View taken on the line 2-2 of Fig. 1: and Fig. 3 is a detail showing the means for securing the wick within the oil tube.

The oiling device embodying my invention comprises a tube 10 having secured thereto a finely perforated leather flap 11, a covering flap 12, and an oil conducting wick 13. The flaps 11 and 12 are secured to the tube 10 by clamping bars 11 and 12 fastened by screws to the sides of the tube.

The wick 13 projects through a slot 14 in the tube 10 and is shown in the form of a loop having the free ends 15 extending downward between the flaps 11 and 12. The folded portion of the wick is retained within the tube 10 by a rod 16 shown in detail in Fig. 3. This rod is corrugated longitudinally and is provided at one end with a recurved portion 17 the purpose of which will be hereinafter explained. The corrugations of the rod 16 prevent the rod from being drawn tightly into the slot 14 and thereby cutting off the oil supply.

The tube 10 is provided with a plurality of oil cups 18, the flow of oil from which may be regulated by screws 19. The tube 10 is furthermore provided with a cylindrical bearing member 20 at one end and at the other end with a threaded plug 21 closing the end of the tube. The plug 21 is provided with a head 22 to which a Wrench may be applied and with the cylindrical extension 23 which provides a bearing for the right hand end of the tube.

When in use the oil tube is mounted above the rotating cylindrical cutter shown diagrammatically at 24 in Fig. 2 and may be provided upon an extension of the bearing member 20 with an arm 25 which is pressed yieldingly against a rotating cam 26 by a spring 27. The rotation of the cam produces a slight oscillation of the oil tube and thereby varies the point at which the perforated leather flap 11 contacts with the rotating cutter 24. Under ordinary conditions, the tube 10 does not act as a reservoir of oil but rather as a distributing device by which the oil fed from the oil cups 18 is conveyed to the wick 13 throughout its length.

The numeral 28 indicates the ledger blade, between which and the rotating cutter the cloth A passes during the shearing operat1on.

For cleaning purposes, the plug 21 may be removed and the rod 16 may be withdrawn by means of the recurved portion 17 The wick 13 may then be removed and a new one substituted as desired.

The utility of my invention is not confined to a cloth shearing machine as it may be used to advantage in any machine in which it is desired to provide a continuous supply of oil for a rotating cylindrical member. I/Vhere I have used the term rotatable tool in the appended claims, I intend it to cover broadly any rotatable cylindrical member, whether provided with cutting edges or not.

I am aware that many modifications of my device may be made by those skilled in the art within the spirit and scope of my invention and I do not wish to be limited to the details disclosed herein, but

Patented Apr. 7, 1914.

What I do claim is 1. An oiling device for a rotatable tool, having in combination a tube, means to feed oil to said tube, a perforated flap secured to said tube and contacting with said tool and a wick to convey oil from said tube to said 2. An oiling device for a rotatable tool, having in. combination a tube, means to feed oil to said tube, a perforated flap secured to said tube and contacting with said tool, a clamping bar for securing said flap to said tube, a Wick to convey oil from said tube to said flap, and means to oscillate said tube.

3. An oiling device for a rotatable tool, having in combination a tube, means to feed oil to said tube, means to regulate the rate of feed of the oil, a perforated flap secured to said tube, and a wick for conveying the oil to said flap, said tube having a slot at one side and said wick being secured withip said tube and projecting through said s ot.

4. An oiling device comprising a slotted 7 ing flap also secured thereto, and a wick having one end confined within said tube and having its other end extending between said flaps and conducting oil from said tube to said oiling flap. p

5. In an olling device, a slotted oil tube, a wick forming a loop with the ends projecting through the slot in said tube, and a corrugated wire Within said tube extending through the loop of the Wick and preventing withdrawal of the wick from the tube.

6. In an oiling device, a slotted tube having a removable plug at one end, a wick forming a loop with the ends projecting through the slot in said tube and 'a rod within the tube extending through the .loop of the wick and having a recurved end by which it may be withdrawn from the loop after the plug is removed from the tube.

In testimony whereof I have hereunto set my hand, in the presence of two subscribing witnesses.

JAMES CATTERALL.
